I have installed bitcoin core (23.0) on a virtual machine (Debian GNU/Linux 10, x86_64) and tried to start the testnet initial block download. Unfortunately,a few days ago blockchain sync is stuck on a particular block 4032 and constantly reports following lines

2022-08-03T18:58:26Z Synchronizing blockheaders, height: 2262031 (~99.69%)
2022-08-03T18:58:26Z Peer=6 is stalling block download, disconnecting
2022-08-03T18:58:26Z Synchronizing blockheaders, height: 2264031 (~99.69%)
2022-08-03T18:58:32Z New outbound peer connected: version: 70015, blocks=2314713, peer=16 (outbound-full-relay)

This problem is not present on mainnet and my bitcoin.conf currently looks simply this way

testnet=1
prune=550

What I've already tried:

  1. Run bitcoind with -maxconnections=1
  2. Run bitcoind with -reindex
  3. Tried different configurations of bitcoin.conf
  4. Delete .bitcoin data directory and restart bitcoind
  5. invalidate block

all steps were unsuccessful :'(

Stuck on this

I am ready to provide further information and would appreciate if someone could help with this issue! Also, I am quite a newbie, so I could be missing something obvious.

With listen=0 and after removing datadir testnet3:

I can't reproduce this, I can sync fine on testnet beyond this point.

Did you delete the correct datadir (.bitcoin/testnet3) in step 4? And did it then start syncing headers from 0% (you can check debug.log in the datadir folder) and get stuck at the same point again?

What does bitcoin-cli -testnet getchaintips say when you are stuck?

  • Yes, I removed .bitcoin/testnet3, and then the sync stuck on the exact same block again. I even reimaged the virtual machine, but that didn't help either. The download has stopped at the same point again, and I'm getting these stall messages.

    If you run with -debug, do you get more relevant messages in debug.log?

    I noticed from your screenshot that you have 1 inbound peer, which may be doing something weird. Maybe you could check if deleting the datadir and temporarily disabling inbound peers (listen=0 in your bitcoin.conf) changes anything?

    Can you see in the logs (with -debug enabled) if you get block 4033 ("00000000db623a1752143f2f805c4527573570d9b4ca0a3cfe371e703ac429aa") but fail to validate it for some reason? Otherwise, I'm out of ideas, sorry.

I appreciate everyone's helpful comments, but I have had no luck solving this problem in a "clean" way. Since I tried to run the nodes on the university's virtual machines, I suspect the problem could be related to networking (firewall or router settings). Also important to note is that on the mainnet the initial block download went smoothly (explanation is possible here).

So my hotfix was to run the test nodes via Tor. With this set-up, the initial block download continued and succeeded.
